Dan was the on-call technician when we were installing our Thermofloor pads, on a Sunday. He responded to the call promptly, was patient and helpful, and made himself available for further questions. I texted him at least one more time on Sunday, and got a prompt, helpful response. I also emailed him, and got a response the next day, and he checked in a couple more times with me, unprompted, to see if I had any more questions. He really gave us first-rate support.
